Abstract
The aggregation-induced emission (AIE) properties of a systematic series of naphthalene diimides (NDIs) varying the chain length at the imide positions have been studied. A solvophobic collapse of NDI units through the flash injection of THF NDI solutions in sonicating water triggers the formation of stable suspensions with enhanced fluorescence emissions. Shorter chains favor the π-π stacking of NDI units through H-aggregation producing a strong AIE effect showing remarkably high quantum yields that have not been observed for non core-substitued NDIs previously. On the other hand, NDIs functionalized with longer chains lead to more disordered domains where π-π stacking between NDI units is mainly given by J-aggregation unfavoring the AIE effect.

Abstract
In this paper, the synthesis of a naphthalene diimide (NDI) derivative with a donor-acceptor-donor (D-A-D) molecular structure substituted with a long alkyl chain (12 carbons) containing naphthalene hydrazide at the imide position is reported. The reduced emission quantum yield (φf = 0.01-0.03) of the NDI derivative in various solvents indicates the perturbation of the electronic state of π-electron deficient NDI (A) by the peripheral naphthalene (D) units. The investigation of the influence of the alkyl chain and naphthalene substituent on the self-assembling properties of the NDI derivative reveals an isodesmic mode of self-assembly in a chloroform/methylcyclohexane (CHCl3/MCH, 1 : 9, v/v) mixture. The self-assembling nature of the NDI derivative also results in the formation of an organogel in the CHCl3/MCH (1 : 9, v/v) mixture, and gel formation is well-comprehended by techniques such as P-XRD, rheological studies, and FT-IR measurements. Furthermore, radical anion (NDI˙-) formation of π-acidic NDI was used as a sensing tool for hydrazine by a fluorescence "turn-on" (φf = 0.12) method in the solution (DMSO), film, and gel state with a detection limit of 284.1 ppb in DMSO and 32 ppb in the gel state.

Abstract
Two naphthalene diimide containing molecules, one with a covalently linked peptide (P1) and the other with a covalently attached amino acid residue and a diamine moiety (P2), have been chosen in such a way that the number of intervening amide groups and the centrally located imide moieties are the same, and their molecular formulae are also identical. However, the positions of the amide groups are different in these two molecules and this can dictate a different behaviour in molecular assembly and gelation processes for each of the individual NDI-appended peptide (P1) and pseudo-peptide (P2). The molecule P1 with an attached peptide moiety and the intervening -CO-NH groups forms an organogel in a mixture of chloroform-methylcyclohexane at a very rapid rate and the mechanical strength of the gel is quite high, whereas the molecule P2, containing the amino acid and diamide moieties, and with the intervening -NH-CO groups forms an organogel in a relatively much slower rate in chloroform-methylcyclohexane mixture. The mechanical strength of the P2 gel is significantly lower compared to that of the P1 gel at the same concentration and solvent system. The minimum gelation concentration of P1 is much smaller than that of P2 in the same solvent system. The thermal stability of the P1 gel is higher than that of the P2 gel at the same concentration and solvent system. However, both of these gels form J-type aggregates in a mixture of chloroform-methylcyclohexane with a red shift in the UV-vis spectrum. The gelator P1 exhibits enhanced fluorescence compared to that of P2 at a fixed concentration and in the same solvent system (mixture of chloroform-methylcyclohexane, 5 : 95 (v/v)). The lifetime and quantum yield of the P1 gel are also significantly higher than those of the P2 gel under similar gelation conditions. Moreover, both P1 and P2 are found to exhibit significant semiconducting behaviours in their dried/xerogel states. It is important to note that the stronger gel P1 exhibits relatively better semiconducting behaviour than the weak gel P2. Interestingly, the self-assembly, gelation, photoluminescence and electrical conductivity are different for the gels obtained from these two molecules. This indicates the role of the amide bond and its linkage (whether -CONH/-NHCO) in the self-assembly, gelation and optoelectronic behaviour of these molecules in their assembled states.

Abstract
This study convincingly demonstrates a unique example of the self-assembly of a naphthalene diimide (NDI)-appended peptide into a fluorescent J-aggregate in aqueous media. Moreover, this aggregated species shows a remarkable yellow fluorescence in solid state, an unusual phenomenon for NDI-based compounds. The aggregated species has been characterized using transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy, X-ray diffraction, time-correlated single proton counting (TCSPC), UV-vis, and photoluminescence studies. TEM images reveal cross-linked nanofibrillar morphology of this aggregated species in water (pH 7.4). TCSPC study clearly indicates that the aggregated species in water has a higher average lifetime compared to that of the non-aggregated species. Interestingly, this NDI-based peptide shows H+ ion concentration-dependent change in the emission property in water. The fluorescence output is erased completely in the presence of an alkali, and it reappears in the presence of an acid, indicating its erasing and rewritable property. This indicates its probable use in authentication tools for security purposes as a rewritable fluorescence color code. This NDI-appended peptide-based molecule can be used for encryption of information due to erasing and rewritable property of the molecule in the aggregated state in aqueous medium.

Abstract
A new derivative of naphthalene diimide (NDMI) was synthesized that displayed optical, electrical, and visual changes exclusively for the most widespread nitroexplosive and highly water-soluble toxicant picric acid (PA) due to strong π-π interactions, dipole-charge interaction, and a favorable ground state electron transfer process facilitated by Coulombic attraction. The sensing mechanism and interaction between NDMI with PA is demonstrated via X-ray diffraction analysis, (1)H NMR studies, cyclic voltammetry, UV-visible/fluorescence spectroscopy, and lifetime measurements. Single crystal X-ray structure of NDMI revealed the formation of self-assembled crystalline network assisted by noncovalent C-H···I interactions that get disrupted upon introducing PA as a result of anion exchange and strong π-π stacking between NDMI and PA. Morphological studies of NDMI displayed large numbers of single crystalline microrods along with some three-dimensional (3D) daisy-like structures which were fabricated on Al-coated glass substrate to construct a low-cost two terminal sensor device for realizing vapor mode detection of PA at room temperature and under ambient conditions. Furthermore, an economical and portable electronic prototype was developed for visual and on-site detection of PA vapors under exceptionally realistic conditions.

Abstract
This study reports the synthesis and photophysical properties of a star-shaped, novel, fluoranthene-tetraphenylethene (TFPE) conjugated luminogen, which exhibits aggregation-induced blue-shifted emission (AIBSE). The bulky fluoranthene units at the periphery prevent intramolecular rotation (IMR) of phenyl rings and induces a blueshift with enhanced emission. The AIBSE phenomenon was investigated by solvatochromic and temperature-dependent emission studies. Nanoaggregates of TFPE, formed by varying the water/THF ratio, were investigated by SEM and TEM and correlated with optical properties. The TFPE conjugate was found to be a promising fluorescent probe towards the detection of nitroaromatic compounds (NACs), especially for 2,4,6-trinitrophenol (PA) with high sensitivity and a high Stern-Volmer quenching constant. The study reveals that nanoaggregates of TFPE formed at 30 and 70% water in THF showed unprecedented sensitivity with detection limits of 0.8 and 0.5 ppb, respectively. The nanoaggregates formed at water fractions of 30 and 70% exhibit high Stern-Volmer constants (Ksv=79,998 and 51,120 M(-1), respectively) towards PA. Fluorescence quenching is ascribed to photoinduced electron transfer between TFPE and NACs with a static quenching mechanism. Test strips coated with TFPE luminogen demonstrate fast and ultra-low-level detection of PA for real-time field analysis.
