A real-time dynamic holographic material using a fast photochromic molecule

Abstract

We have developed a real-time, dynamic holographic material that exhibits rapid colouration upon irradiation with UV light and successive fast thermal bleaching within tens of milliseconds at room temperature. Photochromic polymer films were prepared by a simple solution-casting method from the benzene solution of the mixture of the photochromic molecule, poly(ethyl acrylate), and poly(phenoxyethyl acrylate). The real-time control of holographic images using the photochromic polymer film yields a speed equivalent to the time resolution of the human eye. This new type of dynamic holographic material based on fast photochromism opens up an exciting new area of research in the future development of a large dynamic 3D display.

“…Однако термически релаксирующие фотохром-ные биимидазодилы XVII, характеризующиеся време-ни жизни фотоиндуцированной формы около десят-ков миллисекунд (рис. 7), могут представлять прак-тический интерес для динамической голографии [116]. В качестве полимерного связующего в таких средах использовалась смесь полиэтил-и полифеноксиэтил-акрилаты.…”

Optical, electrochemical, and thermal behavior of polybenzoxazine copolymers incorporated with tetraphenylimidazole and diphenylquinoline

“…Polymeric materials with unique combination of both electrochemical and optical properties have attracted tremendous technological interest in the past few decades due to increasing need for stability, low cost, structural flexibility, and process ability. Various designing methods have been employed to achieve efficient semiconducting properties in polymers with potential applications in the field of optical storage media, photorefractive devices, photovoltaic devices, light emitting diodes, and many other photonic systems. Numerous reports are available in the literature about the synthesis for optoelectronic properties of conjugated polymers and systems .…”

However, less attention was given to non‐conjugated polymers, the semiconducting property of which is based on the charge hopping from one localized site to another in the direction of optoelectronic field.…”

Recent advances in holographic recording media for dynamic holographic display

“…In 2012, Ishii et al, from Aoyama Gakuin University and Japan Science and Technology Agency introduced a photochromic [2.2]paracyclophane (PC)-bridged imidazole dimer [29]. This dimer, upon the exposure to UV light, exhibits coloration from colorless to blue, with its C-N bond between the two imidazole rings being homolytically cleaved to give a pair of imidazolyl radicals.…”
