Abstract
Magic-sized clusters (MSCs) can be isolated as intermediates in quantum dot (QD) synthesis, and they provide pivotal clues in understanding QD growth mechanisms. We report syntheses for two families of heterogeneous-atom-incorporated InP MSCs that have chlorine or zinc atoms. All the MSCs could be directly synthesized from conventional molecular precursors. Alternatively, each series of MSCs could be prepared by sequential conversions. 386-InP MSCs could be converted to F360-InP:Cl MSCs, then to F399-InP:Cl MSCs. Similarly, F360-InP:Zn MSCs could be converted to F408-InP:Zn MSCs, then to F393-InP:Zn MSCs. As the conversion proceeded, evolution from uni-molecule-like to QD-like characters was observed. Early stage MSCs showed active inter-state conversions in the excited states, which is characteristics of small molecules. Later stage MSCs exhibited narrow photoinduced absorptions at lower-energy region like QDs. The crystal structure also gradually evolved from polytwistane to more zinc-blende.

Abstract
The surface extension of all-carbon based bowl-shaped molecules, such as corannulene and sumanene, to synthesize even larger buckybowls has been widely studied, leaving other concave compounds with heteroatoms less considered. Herein we present a highly curved molecule synthesized via stepwise cyclization of fjords of a bisacridone derivative. Crystallographic analysis unambiguously confirmed a boat-shaped structure with deformed bottom benzene ring. Theoretical calculation unravels an inversion process with an S-shaped transition structure rather than a planar one. The enlarged boat demonstrates interesting properties, such as red shifts in absorption and emission spectra, enhanced emission intensity, and convergent frontier molecular orbital energy levels, in comparison to the related concave N-heterotriangulene.

Abstract
meso-Free BIII 5,10-bis(p-dimethylaminophenyl)subporphyrins were synthesized. They display red-shifted absorption and fluorescence spectra, bathochromic behaviors in polar solvents, a high fluorescence quantum yield (ΦF =0.57), and a small HOMO-LUMO gap mainly due to destabilized HOMO as compared with meso-free BIII 5,10-diphenylsubporphyrin. This subporphyrin serves as a nice precursor of various meso-substituted BIII subporphyrins such as BIII meso-nitrosubporphyrin, BIII meso-aminosubporphyrin, and meso-meso' linked BIII azosubporphyrin dimer. Reactions of meso-free BIII subporphyrins with NBS or bis(2,4,6-trimethylpyridine)bromonium hexafluorophosphate gave meso-meso' linked subporphyrin dimers, often as a major product along with meso-bromosubporphyrins.

Abstract
An intramolecular oxidative aromatic coupling of meso-substituted porphyrins bearing electron-rich aromatics was the focus of investigation. The formation of C–C bond at [Formula: see text]-position for macrocycles bearing dimethoxynaphthalene moiety was achieved. It was established that Fe(ClO[Formula: see text]O induced only single cyclodehydrogenation whereas Fe(OTf)[Formula: see text] had the ability to remove four hydrogens and four electrons forming doubly-fused porphyrin. Both Fe(ClO[Formula: see text]O and Fe(OTf)[Formula: see text] were confirmed superior to FeCl[Formula: see text] as they ensured efficient oxidation process without concomitant chlorination of the products. We have proven that the trans-A[Formula: see text]B[Formula: see text]-porphyrin with two indole moieties do not form any stable products under such reaction conditions. The single fusion with dimethoxynaphthalene moiety has a comparable effect on absorption spectra [Formula: see text]. the Q-band of Ni-complexes is shifted to 650 nm. The Ni-porphyrin fused with two naphthalene units had bathochromically shifted Q-bands to 733 nm.

Abstract
Acetylene and trans-ethylene bridged BIII -subporphyrin dimers were synthesized by cross-coupling reactions of meso-bromo BIII subporphyrin. These dimers display perturbed and red-shifted absorption spectra reaching around 750 nm and fluorescence reaching at around 850 nm with high quantum yields of 0.39 and 0.47, respectively. DFT calculations have revealed that the HOMOs and the LUMOs of both dimers are spread over the two subporphyrin units as an indication of effective conjugation between the two subporphyrin units. The large Stokes shifts and characteristic pico-second time-resolved transient absorption spectra indicated that the S1 -states of the dimers relax with structural changes, which are larger for the trans-ethylene bridged dimer.

Abstract
Charge-transfer (CT) complexes of near-infrared absorbing systems have been unknown until now. Consequently, structural similarities between donor and acceptor are rather important to achieve this phenomenon. Herein, we report electron donors such as non-fused diporphyrin-anthracene (DP), zinc diporphyrin-anthracene (ZnDP) and fused zinc diporphyrin-anthracene (FZnDP) in which FZnDP absorbs in NIR region and permits a CT complex with the electron acceptor, perylene diimide (PDI) in CHCl3 exclusively. UV/Vis-NIR absorption, 1 H NMR, NOESY and powder X-ray diffraction analysis demonstrated that the CT complex formation occurs by π-π stacking between perylene units in FZnDP and PDI upon mixing together in a 1:1 molar concentration in CHCl3 , unlike non-fused ZnDP and DP. TEM and AFM images revealed that the CT complex initially forms nanospheres leading to nanorods by diffusion of CH3 OH vapors into the CHCl3 solution of FZnDP/PDI (1:1 molar ratio). Therefore, these CT nanorods could lead to significant advances in optical, biological and ferroelectric applications.
