Second-Order Nonlinear Optical Dendrimers and Dendronized Hyperbranched Polymers

Abstract

Second-order nonlinear optical (NLO) dendrimers with a special topological structure were regarded as the most promising candidates for practical applications in the field of optoelectronic materials. Dendronized hyperbranched polymers (DHPs), a new type of polymers with dendritic structures, proposed and named by us recently, demonstrated interesting properties and some advantages over other polymers. Some of our work concerning these two types of polymers are presented herein, especially focusing on the design idea and structure-property relationship. To enhance their comprehensive NLO performance, dendrimers were designed and synthesized by adjusting their isolation mode, increasing the number of the dendritic generation, modifying their topological structure, introducing isolation chromophores, and utilizing the Ar-Ar self-assembly effect. To make full use of the advantages of both the structural integrity of dendrimers and the convenient one-pot synthesis of hyperbranched polymers, DHPs were explored by utilizing low-generation dendrons as big monomers to construct hyperbranched polymers. These selected works could provide valuable information to deeply understand the relationship between the structure and properties of functional polymers with dendritic structures, but not only limited to the NLO ones, and might contribute much to the further development of functional polymers with rational design.

Synthesis of chromophores and polyimides with a green chemistry approach for second‐order nonlinear optical applications

“…A review article was published by Li et al to demonstrate the new design strategies for second‐order NLO polymers with a concept of suitable isolation group. Very recently, a comprehensive review on second‐order NLO dendrimers and dendronized hyperbranched polymers was reported in the literature . This review mainly emphasized on the synthetic process with possible tunable topological structures of NLO dendrimers for the enhancement of second‐order coefficients.…”

“…The design and search of novel promising chromophores materials for the optoelectronic applications is very important for modern organic materials science engineering due to their promising parameters with respect to high-speed and broadband telecommunication technology [1][2][3][4][5][6]. For today different materials are just used for the nonlinear optical and electrooptical laser modulators [7][8][9][10][11][12][13].…”

New ROMP Synthesis of Ferrocenyl Dendronized Polymers

“…[54,55] As the merger of the two families of dendrimers and polymers, dendronized polymers are macromolecules in which perfectly branched dendrons are attached as pendant groups onto a linear polymer backbone affording a structure where many active termini surround a single chain. [56][57][58][59][60][61] Due to their unique tailorable structures and physicochemical properties, [62][63][64][65][66][67][68] dendronized polymers have attracted significant attention in the field of nanoscience and bioscience. [56][57][58][59][60][61][62][63][64][65][66][67][68][69][70] Few reports have focused on the synthesis and application of dendronized metallopolymers; [71,72] however, presumably due to their challenging synthesis.…”
