Abstract

Abstract : A phenanthrene-based diarylethene linker with linear pyridyl connectivity, 4, 4′-(9, 10-bis(2, 5-dimethylthiophen-3-yl)phenanthrene-2, 7-diyl)dipyridine linker (TPDPy ) was prepared and used to synthesize an air-stable metal–organic framework, UBMOF -3, (Zn3 (BDC)3 (TPDPy)1 (DMF)1.5 ). Abstract : A phenanthrene-based diarylethene linker with linear pyridyl connectivity, 4, 4′-(9, 10-bis(2, 5-dimethylthiophen-3-yl)phenanthrene-2, 7-diyl)dipyridine linker (TPDPy ) was prepared and subsequently used to synthesize an air-stable metal–organic framework, UBMOF -3 (Zn3 (BDC)3 (TPDPy)1 (DMF)1.5, BDC = 1, 4-benzenedicarboxylate, DMF = N, N -dimethylformamide). Upon irradiation with ultraviolet light, this photo-responsive framework, composed of terephthalate, TPDPy, and zinc pinwheels, exhibits strong linear dichroism consistent with the crystal structure. Activation (desolvation) of the crystal leads to a significant change in the crystal structure that improves the ability to crystallographically resolve the photochromic linker.
