Poly molecular design

In the present chapter, emphasis is placed on the authors recent studies concerning the molecular design and optical/photochemical properties of Frechet-type poly(benzyl ether) dendrimers. 

Poly(acetylenes) [16], poly(diacetylenes) [17], poly(phenylenes) [18] and poly(phenylenevinylenes) [19] have been proposed as main chains. The new molecular design that has to be developed now concerns the question of where to place the open-shell centres on the pendents in the side chains of the polymers (Iwamura, 1987, 1988 Iwamura and Murata, 1989 Murata et a/., 1987 Ovchinnikov, 1978 Tyutyulkov et al., 1985 Yamaguchi et al., 1987).

There are examples of poly(arylene ether)s, polyimides, and polyamides having l,l -binaphthy-lene-2,2 -diyl or biphenylene units that introduce chiral twists in the polymer chain. The chiral groups are expected to make the entire chain take a helical conformation. Earlier studies based on similar molecular designs are cited in Mi et...
