Studies of the non-linear optical properties of classical AIEgens are rare, despite their important potential applications in organic composite photonic circuits. Here, we present experimental results, supported by theoretical calculations, of the non-linear optical (NLO) properties of TPE and its halogenated derivates.

Acid Adduct

Two adducts of 2-aminobenzothiazole and one of 2-amino-2-thiazoline with aromatic carboxylic acids have been synthesized and their X-ray crystal structures determined. These are 2-aminobenzothiazole with 3,5-dinitrobenzoic acid (the 1 : 1 adduct hydrate) (1), and 3-aminobenzoic acid (1 : 1) (2), and 2-amino-2-thiazoline with 2-aminobenzoic acid (1 : 1) (3). Compound (1) is a non-centrosymmetric proton-transfer complex and gave a signal of 0·30 relative to urea when tested for second-order non-linear optical properties. Compound (3) is also a proton-transfer complex but (2) is not.

Two novel 1,3,5-trisubstituted pyrazoline derivatives—1-acetyl-3-(4-methoxyphenyl)-5-(6-methoxy-2-naphthyl)-pyrazoline (2a) and 1-(4-nitrophenyl)-3-(4-methoxyphenyl)-5-(6-methoxy-2-naphtyl)-pyrazoline (2b)—were synthesized and their structures were determined by single crystal X-ray crystallography. Both of the two crystals exhibit twisted structures due to the large dihedral angles between the pyrazolinyl ring and the aromatic ring at the 5-position (88.09° for 2a and 71.26° for 2b). The optical–physical properties of the two compounds were investigated. The fluorescent emission of 2b arises from the 1,3-disubstituted pyrazoline chromophores and exhibits a red shift in polar solvents and solid-state, which could be attributed to photo-induced intramolecular charge transfer (ICT) from N1 to C3 in the pyrazoline moiety and the intermolecular interactions within the crystal. The fluorescent emissions of 2a (λmax 358–364 nm) in solvents and solid-state both come from 6-methoxy-2-naphthyl chromophores, which are fairly insensitive to the solvent polarity.
