The conformations of the E-forms of photochromic furylfulgides with a methyl substituent (1E) and an isopropyl substituent (2E) were investigated by X-ray crystallographic analyses, NMR measurements, and molecular orbital (MO) calculations in relatio

Furylfulgides with different sizes of alkyl substituents were synthesized and their photochromic properties were examined. While the quantum yield of coloring reaction increased and the quantum yield of the E-to-Z isomerization decreased as the steri

Quantum yields of photoreactions of furylfulgides having Me, Et, n-Pr, or i-Pr on the furylalkylidene moiety were measured. The E–Z isomerization was greatly suppressed and the cyclization was accelerated when the alkyl group (R) became bulkier. Wh

The formation mechanism of microporous film which was obtained by casting a methyl ethyl ketone (MEK)/N,N-dimethlformamide (DMF) solution of an electron beam (EB)-reactive urethane-acrylamide prepolymer was discussed. The porosity and crystallinity i

The morphology and aggregation structure of electron beam (EB)-cured microporous polyurethane-acrylamide film was investigated. The urethane-acrylamide prepolymer was synthesized by the reaction of poly(butylene adipate)diol, 4,4′-diphenylmethane d
