Abstract ：
Based on 10-methyl-10H-phenothiazine-5,5-dioxide unit as an acceptor and 9,10-dihydro-9,9-dimethyl-acridine (DMAC) or phenoxazine (PXZ) as donors, four intramolecular charge transfer (ICT) compounds were designed and synthesized by Buchwald-Hartwig cross coupling reactions. Their ground-state geometries were optimized with density functional theory (DFT) at B3LYP level and vertical transition energies were calculated using the optimal Hartree-Fock (HF) exchange method. Resulting compounds were characterized by fourier transform infrared (FT-IR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, liquid chromatography-mass (LC-MS) spectrometry and hybrid quadrupole time-of-flight mass spectrometry (QTOF). Their photophysical properties were systematically investigated. The results show that compound 2a has maximum emission wavelength (lambda(max)) of 422 nm in toluene and its oxygen-free one has photoluminescence quantum yield (PLQY) of 0.367. The lambda(max) and PLOY for 1a and 1b are 455 nm, 0.083 and 511 nm, 0.098, respectively. Transient photoluminescence decay curves for 5 wt% 1a and 1b doped in PMMA films indicate that their delayed fluorescence lifetimes are 5.78 and 20.00 mu s, respectively. According to the time-resolved fluorescence and phosphorescence spectra of 1a and 1b doped in PMMA films at 77 K, their energy gaps (Delta E-ST) between the lowest singlet state (S-1) and the lowest triplet excited state (T-1) are determined to be 0.203 and 0.177 eV, respectively, which are consistent with the theoretical values 0.232 and 0.295 eV calculated with time-dependent density functional theory (TD-DFT). As a result, la and 1b are expected to be potential thermally activated delayed fluorescence (TADF) materials. The electrochemical properties of the four compounds in dichloromethane solution were determined through cyclic voltammetry using TBAPF(6) as supporting electrolyte and ferrocene as internal standard. The HOMO energy levels of 1a, 1b, 2a and 2b are estimated to be -5.369, -5.111, -5.412 and -5.075 eV, respectively. The thermal properties of the four compounds were investigated by thermal gravimetric analysis under nitrogen atmosphere at a heating rate of 10 degrees C.min(-1) and all compounds show good thermal stability with decomposition temperatures above 420 degrees C.

Abstract ：
Micro-/nano-structural polyanilines (PANI) with high recovered yield (90%) were prepared by template-free chemical oxidative polymerization in presence of HCl as dopant. The morphologies, structures and properties of micro-/nano-structural PANI were characterized by means of FESEM, TEM, FTIR, UV-Vis and four-probe technique. PANI nanofibers of 30-43 nm in diameter and 186-600 nm in length are prepared in 1.0 mol/L HCl at 0°C for 24 h (without stirring). PANI nanofibers of 43-57 nm in diameter and 0.86-1.43 μm in length, and microspheres (1.2-2.2 μm in outer diameter) are synthesized by prolonging polymerization time for 72 h in 1.0 mol/L HCl at 0°C (without stirring). PANI microspheres are constructed from their own nano-fibers by self-assembling. The obtained HCl-doped micro-/nano-structural PANI is good in room-temperature electroconductivity of 5.0 S/cm and attractive in solvatochromism in various solvents.
