Intercalation and Photochemical Behavior of Azobenzene Derivatives with Layered Polymer Crystals as the Organic Host

Abstract

A photofunctional organic solid was fabricated by the intercalation of azobenzene derivatives containing an amino group into poly(muconic acid) as the layered polymer crystals. The organic intercalation and photoisomerization behaviors depended on the structure of the spacer between the azobenzene and amino groups of the guest.

Orientational Control of Guest Molecules in an Organic Intercalation System by Host Polymer Tacticity

“…However, a limited number of examples have been reported as the intercalation systems consisting of only organic compounds 5. We have already demonstrated that a layered PMA is available as the host compound for the intercalation of various organic guests such as alkylamines,4 unsaturated amines,6 azo‐containing amines,7 and other functional amines,4 as well as the metal cations as the inorganic guests 8…”

Photochromic Intercalation Compounds

“…In addition to the systems based on photochrmoic compounds in such transparent solid matrices as polymers and silicas, vairous supramolecular systems have been utilized in order to organize photochrmoic moeity in a controlled manner, Zeolites and mesoporous materials have been used as matrices for constructing photofunctional hybrids[1-2, [4][5][47][48][49][50][51]. Chemical interactions between matrices and photochrmoic dyes have been designed to construct host-guest photochrmoic materials [52][53][54][55]. As a recent example of solid-state photochromic host guest system, which is relevant to the intercalation compouds, a metal-organic framework (MOF; or a porous coordination polymer PCP) with azobenzene group introduced to the organic linker has been developed for reversible change in CO2 uptake upon external stimuli [56].…”

Reactions of 1,3-Diene Compounds in the Crystalline State

“…The topochemical polymerization of 1,3-diene monomers based on polymer crystal engineering can be used not only for tacticity but also for the other chain structures such as molecular weight [102], ladder [84] or sheet [103] structures, and also polymer layer structures using intercalation reactions [104][105][106][107]. Some mechanical and structural properties have already been revealed with well-defined and highly or partly crystalline polymers [108][109][110][111].A totally solvent-free system for the synthesis of layered polymer crystals was also reported [112].…”
