Abstract
Carbazole-based, π-conjugated donor-acceptor fluorophores were synthesized by integrating imidazole/thiazole units. Then, we investigated the impact of subtle structural changes on fluorescence properties. Carbazole integrated with imidazole (Cz-I) and carbazole integrated with thiazole (Cz-T) showed strong fluorescence in solution (quantum yield (Φ f) = 0.18 (Cz-I) and 0.14 (Cz-T) compared with the standard quinine sulfate) and solid-state (Φ f = 8.0% (Cz-I) and 14.6% (Cz-T)). Cz-I showed relatively more blue-shifted emission in solution compared with the solid-state (λ max = 417 nm (CH3CN) and 460 nm (solid)). Cz-T exhibited deep-blue emission in the solid-state compared with solution (λ max = 455 nm (CH3CN) and 418 nm (solid)). Interestingly, Cz-T exhibited a drastic change in fluorescence in organic solvents (CH3CN, THF, CH3OH, DMSO) with a low percentage (1%) of water. Cz-I showed reversible fluorescence switching between two fluorescence states upon exposure to trifluoracetic acid (TFA)/ammonia (NH3). In contrast, Cz-T displayed reversible/self-reversible off-on fluorescence switching upon exposure to TFA or NH3. Mechanofluorochromic studies of Cz-I showed a slight reduction in fluorescence intensity upon crushing and reversal to the initial state upon heating. Cz-T exhibited off-on reversible/self-reversible fluorescence switching upon crushing/heating. Computational studies indicated that thiazole integration improved the electron-withdrawing characteristics compared with imidazole and contributed to contrasting fluorescence responses. Thus, a simple change of nitrogen with sulfur produced contrasting self-assembly in the solid-state that led to different functional properties and stimuli-induced fluorescence switching.

Abstract
The bis-(anil) mol-ecule of the title compound, C47H32N2O2·C6H4Cl2, contains two anil fragments in the enol-enol form, exhibiting intra-molecular O-H⋯N hydrogen bonds. The two hy-droxy-naphthalene ring systems are approximately parallel to each other with a dihedral angle of 4.67 (8)° between them, and each ring system makes a large dihedral angle [55.11 (11) and 48.50 (10)°] with the adjacent benzene ring. In the crystal, the bis-(anil) mol-ecules form an inversion dimer by a pair of weak C-H⋯O inter-actions. The dimers arrange in a one-dimensional column along the b axis via another C-H⋯O inter-action and a π-π stacking inter-action between the hy-droxy-naphthalene ring system with a centroid-centroid distance of 3.6562 (16) Å. The solvent 1,2-di-chloro-benzene mol-ecules are located between the dimers and bind neighbouring columns by weak C-H⋯Cl inter-actions. Theoretical prediction of potential biological activities was performed, which suggested that the title anil compound can exhibit histone de-acetyl-ase SIRT2, histone de-acetyl-ase class III and histone de-acetyl-ase SIRT1 activities, and will act as inhibitor to aspulvinone di-methyl-allyl-transferase, de-hydro-l-gulonate deca-rboxylase and gluta-thione thiol-esterase.

Abstract
Halochromic isoquinoline attached mechanochromic triphenylamine, N-phenyl-N-(4-(quinolin-2-yl)phenyl)benzenamine (PQPBA) and tris(4-(quinolin-2-yl)phenyl)amine (TQPA), smart fluorescent materials exhibit thermo/mechanochromism and tunable solid state fluorescence and their unusual halochromic response in PMMA matrix have been used for fabricating rewritable and self-erasable fluorescent platforms. PQPBA and TQPA showed strong fluorescence in solution (Φf = 0.9290 (PQPBA) and 0.9160 (TQPA)) and moderate solid state fluorescence (Φf = 20 (PQPBA) and 17% (TQPA). Interestingly, they exhibited a rare temperature (0-100 °C) dependent positive fluorescence enhancement via activating radiative vibrational transition. The deaggregation of PQPBA and TQPA in PMMA polymer matrix lead to the enhancement of fluorescence intensity strongly and fabricated strong blue fluorescent thin films (Φf = 58% (PQPBA) and 54% (TQPA). The halochromic isoquinoline has been exploited for demonstrating reversible off-on fluorescence switching by acid (TFA (trifluoroacetic acid)/HCl) and base (NH3) treatment in both solids as well as PMMA thin films. Importantly, rewritable and self-erasable fluorescent platform has been achieved by make use of unusual fluorescence responses of PQPBA/TQPA with TFA/HCl after exposing NH3. Single crystal and powder X-ray diffraction (PXRD) studies provided the insight on the solid-state fluorescence and external stimuli-induced fluorescence changes.
