Multifunctional photochromic hybrid materials have attracted great attention due to their wide prospects in information storage, molecular switches, and sensors. Herein, three new coordination polymers (CPs) with paramagnetic Mn2+ ions, namely [Mn2(TTVP)(m-BDC)2] (1), [Mn3(TTVP)(p-BDC)3(H2O)2]·0.5H2O (2), [Mn(TTVP)(H2O)4]·(4,4'-BPC)·2H2O (3) been synthesized (TTVP = 2,5-bis(pyridinium-4-yl)thiazolo[5,4-d]thiazole propionate, m-H2BDC isophthalic acid, p-H2BDC terephthalic 4,4'-H2BPC 4,4'-diphenyldicarboxylic acid). Interestingly, under Ultraviolet (UV) light irradiation, these compounds exhibit distinct performances photoinduced electron transfer (PIET) between aromatic carboxylic acids TTVP, as validated by spectroscopic structural analyses. The coloration kinetics final states are finely tuned modulating the number strength of weak interactions donors (EDs) acceptors (EAs). Furthermore, complexes magnetization enhancement at room temperature, while 2 3 reversible fluorescence modulation during coloration-decoloration cycles. introduction photoregulated fluorescent magnetism into PIET presents a promising approach for development multifunctional materials, holding potential range applications.

Photochromic hydrogen-bonded organic frameworks (HOFs) can introduce different luminescent functional groups to achieve synergistic controlled multiple color change properties, which are in great demand for diverse information encryption applications. We report this paper switchable photochromic and photoluminescent dual group HOFs constructed with effects by N,N′-bis(2-phenylalanine)-1,4,5,8-naphthalenediimine (H2PheNDI) benzenecarboximidamide 4,4′-azobis(hydrochloride) (AZBH). The crystal powder of iHOF-41 is orange–red color, be changed black under the irradiation a 365 nm ultraviolet (UV) light source 15 min. photoisomerization rate solution continuous UV 5 h was close 99%. composite membranes properties photochromism photoluminescence when they discolored and, at same time, excite red bright fluorescence. This work achieves construction based on switching biluminescent explores mechanism process as well its practical application encryption.
