Abstract
The reaction of MnIIPc, FeIIPc or FeIIPcCl16 with KCN in the presence of cryptand[2.2.2] yielded dicyano-complexes {cryptand(K+)}2{MII(CN)2(macrocycle2-)}2-·XC6H4Cl2 (M = Mn and Fe, X = 1 and 2) that were used for the preparation of trinuclear assemblies of the general formula {cryptand(K+)}2{MII(CN)2Pc·(ML)2}2-·nC6H4Cl2 (MII = MnII and FeII; n = 1, 4 and 5). These assemblies were formed via coordination of two manganese(II) acetylacetonate (ML = MnII(acac)2, S = 5/2), tris(cyclopentadienyl)gadolinium (ML = Cp3GdIII, S = 7/2) or tris(cyclopentadienyl)neodymium (ML = Cp3NdIII, S = 3/2) units to the nitrogen atoms of bidentate cyano ligands. The N(CN)-Mn{MnII(acac)2} bond is 2.129(3) Å long but the bonds are elongated to 2.43-2.49 Å for tris(cyclopentadienyl)lanthanides. {Cryptand(K+)}2{MnII(CN)2Pc·(MnII(acac)2)2}2-·5C6H4Cl2 (2) contains three Mn(II) ions in different spin states (S = 5/2 and 1/2). Strong antiferromagnetic coupling of spins observed between them with the exchange interaction (J) of -17.6 cm-1 enables the formation of a high S = 9/2 spin state for {MnII(CN)2Pc·(MnII(acac)2)2}2- dianions at 2 K. The estimated exchange interaction between MnII (S = 1/2) and GdIII (S = 7/2) spins in {MnII(CN)2Pc·(Cp3GdIII)2}2- is only -1.1 cm-1, and in contrast to 2, nearly independent GdIII and MnII centers are formed. As a result, no transition to the high-spin state is observed in {MnII(CN)2Pc·(Cp3GdIII)2}2-. The {MnII(CN)2Pc·(Cp3NdIII)2}2- and{FeII(CN)2Pc·(Cp3NdIII)2}2- dianions with Cp3NdIII show a decrease of χMT values in the whole studied temperature range (300-1.9 K). A similar behaviour was found previously for pristine Cp3NdIII and Cp3NdIII·L complexes (L = alkylisocyanide ligand).

Abstract
Reduction methods for the preparation of coordination complexes of titanium(IV) and indium(III) phthalocyanines (Pc) with organic dyes such as indigo, thioindigo, and squarylium dye III (SQ) have been developed, which allow one to obtain crystalline {cryptand(K+ )}{(cis-indigo-O,O)2- TiIV (Pc2- )}(Cl- )⋅C6 H4 Cl2 (1), {cryptand(K+ )}{(cis-thioindigo-O,O)2- InIII (Pc2- )}- ⋅C6 H4 Cl2 (2), and {cryptand(K+ )}{[(SQ)2 -O,O]2- InIII (Pc2- )}- ⋅3.5 C6 H4 Cl2 (3) complexes. The formation of these complexes is accompanied by the reduction of the starting dyes to the anionic state. Transition of trans-indigo or trans-thioindigo to the cis conformation in 1 and 2 provides coordination of both carbonyl oxygen atoms of the dye to TiIV Pc or InIII Pc. SQ is reduced to the radical anion state and forms unusual diamagnetic singly bonded (SQ- )2 dimers in 3. These dimers have two closely positioned carbonyl oxygen atoms coordinated to InIII Pc. Dianionic Pc2- macrocycles have been found in 1-3. The complexes contain two chromophore molecules at one metal center. However, their optical spectra are defined mainly by absorption bands of the metal phthalocyanines.

Abstract
In this study, we have assessed the potential application of dichloro silicon phthalocyanine (Cl2-SiPc) and dichloro germanium phthalocyanine (Cl2-GePc) in modern planar heterojunction organic photovoltaic (PHJ OPV) devices. We have determined that Cl2-SiPc can act as an electron donating material when paired with C60 and that Cl2-SiPc or Cl2-GePc can also act as an electron acceptor material when paired with pentacene. These two materials enabled the harvesting of triplet energy resulting from the singlet fission process in pentacene. However, contributions to the generation of photocurrent were observed for Cl2-SiPc with no evidence of photocurrent contribution from Cl2-GePc. The result of our initial assessment established the potential for the application of SiPc and GePc in PHJ OPV devices. Thereafter, bis(pentafluoro phenoxy) silicon phthalocyanine (F10-SiPc) and bis(pentafluoro phenoxy) germanium phthalocyanine (F10-GePc) were synthesized and characterized. During thermal processing, it was discovered that F10-SiPc and F10-GePc underwent a reaction forming small amounts of difluoro SiPc (F2-SiPc) and difluoro GePc (F2-GePc). This undesirable reaction could be circumvented for F10-SiPc but not for F10-GePc. Using single crystal X-ray diffraction, it was determined that F10-SiPc has significantly enhanced π-π interactions compared with that of Cl2-SiPc, which had little to none. Unoptimized PHJ OPV devices based on F10-SiPc were fabricated and directly compared to those constructed from Cl2-SiPc, and in all cases, PHJ OPV devices based on F10-SiPc had significantly improved device characteristics compared to Cl2-SiPc.

Abstract
The structure of a silicon phthalocyanine having a sheath composed of eight 1,4-isobutoxy, four bidentate 2,3-dibenzobarreleno substituents, and two trans-heptacyclopentylpentacyclooctasiloxy ligands has been determined by X-ray crystallography. The macrocycle in this compound is nearly completely covered by its sheath, but there is a channel in it which is large enough to give small diatomic molecules easy access to the macrocycle. In solution, transient channels exist in the sheath because of molecular vibrations. The structure of the compound also has been determined by a PM6 semi-empirical calculation. Except for one understandable difference, the results from this calculation are in good agreement with the results from the crystal determination. The van der Waals volume of the molecule has been determined from both the crystal and PM6 data by a Monte Carlo method. The amount of steric hindrance present in analogs of the compound in which its isobutoxy substituents are replaced by other alkoxy groups has been examined through calculations based on van der Waals volumes. Possible analogs of this sheathed molecule are suggested in which the sheath may be impenetrable to even small molecules and thus that are highly resistant to attack.

Abstract
By coordination of the metal center of tetraphenylmetalloporphyrins (TPMP) [metal center=Zn(II) or Mn(II)] with pyridyl-based bidentate ligands, namely, N,N'-bis(4-pyridyl)urea (4BPU), N,N'-bis(3-pyridyl)urea (3BPU), and N-(4-pyridyl)isonicotinamide (4PIN), various axially modified tetraarylmetalloporphyrins (AMTAMPs) have been crystallographically characterized in their corresponding lattice inclusion complexes. Nine such inclusion crystals are prepared by crystallizing TPMP and the corresponding bidentate ligands in 1:2 molar ratio from suitable solvent systems. While the metal center Zn(II) of TPMP leads to the formation of both dimeric and monomeric AMTAMPs due to its preference for pentacoordinated geometry, the Mn(II) metal center of TPMP forms both polymeric and discrete hexacoordinated AMTAMPs due to its preference for hexacoordinated geometry. However, there seem to be no control on the formation of a particular AMTAMP. Structural analyses suggest that most of the AMTAMPs display new types of packing in the corresponding inclusion crystals.

Abstract
Heteroporphyrin and -phthalocyanine arrays represent an attractive class of light harvesters and charge-separation systems exhibiting an easy route of synthesis and high chemical stability. In the present work, we report the results of photophysical investigations of two novel non-sandwich-type porphyrin-phthalocyanine heterotriads, in which two meso-tetraphenylporphyrin rings (H2TPP or ZnTPP) are linked to the central silicon atom of a silicon(IV) phthalocyanine core. It was found that the photophysical properties of the triads (H2Tr and ZnTr) in N,N-dimethylformamide (DMF) and toluene are strongly affected by two different types of interaction between the porphyrin (P) and the phthalocyanine (Pc) parts, namely excitation energy transfer (EET) and photoinduced charge transfer. The first process results in appearance of the Pc fluorescence when the P-part is initially excited, and plays a dominant role in fast depopulation of the first excited singlet state of the P moiety. If the first excited singlet state of the Pc-part is populated (either directly or via EET), it undergoes fast depopulation by hole transfer (HT) to the charge-separated (CS) state. In polar DMF, the CS state is the lowest excited state, and the charge recombination occurs directly to the ground state. Using transient absorption spectroscopy, the lifetime of the CS state was estimated to be 30 and 20 ps for H2Tr and ZnTr, respectively. In nonpolar toluene, the energy gap between the first excited singlet state of the Pc-part and the CS state is very small, and back HT occurs in both triads, resulting in appearance of "delayed fluorescence" of the Pc-part with a decay time similar to the lifetime of the CS state (190 and 280 ps for H2Tr and ZnTr, respectively). Since the energy of the CS state of ZnTr in toluene is lower than that of H2Tr, the probability of back HT for ZnTr is lower. This was clearly proved by decay-associated fluorescence spectral measurements.
