Impressive nonlinear optical responses of a cationic porphyrin derivative in a flexible all-polymer Bragg stack on optical Tamm mode coupling

Abstract

Herein, we experimentally demonstrate the enhanced nonlinear optical (NLO) response of 5,15-di(pentafluorophenyl)-10,20-bis(4-N-methylpyridyl)Zn(II) porphyrin, abbreviated as ZnP+, by utilizing Tamm plasmon polaritons formed at the interface between a truncated all-polymeric Bragg...

Highly broadband NLO response of acceptor–donor–acceptor materials with a planar conformation

“…Nonlinear optical (NLO) materials have giant potential application in optical limiting, data storage, opticalcontrollable switching. [1][2][3] Therefore, the materials have attracted considerable attention in recent years. Owing to their advantages of low cost, architectural flexibility and fast response speed, organic nonlinear optical materials are believed to be potentially applicable nonlinear optical materials.…”

Synthesis and the spectral, electrochemical, and nonlinear optical properties of β-dicyanovinyl-appended ‘push–pull’ porphyrins

“…29,30 M. V. Vijisha et al framed cationic porphyrins (ZnP + ) and used them to enhance the TPA coefficient and optical limiting properties. 31 Predominantly, porphyrin chromophores possessing push-pull electronic effects, or π-electron conjugation are known to display higher first-order polarizability. Notably, the presence of an appropriate donoracceptor group separated by the π-network framework gives rise to third-order nonlinear coefficients.…”

Control of near-infrared dye fluorescence lifetime in all-polymer microcavities

“…14 As polymers possess unique flexibility and processability, allpolymer microcavities allowing enhancement effects in combination with the recent leaps in polymer-based devices such as organic LEDs and solar cells, would allow efficiency enhancement of these flexible and solution-processed devices. [15][16][17] The possibility of emission rate control was theorized to be achievable through the use of special polymers or nanocomposites that provide particularly high or low Please do not adjust margins Please do not adjust margins refractive index in dielectric mirrors. 18 While radiative rate control has been routinely achieved in planar microcavities based on inorganic dielectrics, the effect has only recently been confirmed in all-polymer microcavities, partly due to the use of low-index perfluorinated polymers.…”
