- Folded polymers showing J-aggregate were synthesized.
- Folded alternative stacking polymers of two different Ï-units were synthesized.
- Folded staggered stacking polymers of Ï-modules were synthesized.
Three types of folded polymers showing alternative stacking of two different Ï-units (A-3), J-aggregate (J-3), and staggered stacking (S-3) structures of Ï-modules were designed and synthesized using 2-substituted 1,3-diaryl tethering units. The UV-absorbing and fluorescent emission properties of these polymers were investigated and compared to those of the corresponding single structural Ï-molecule component and H-type stacking polymer (H-3). These three types of polymers exhibited unique optical properties as a result of a distinctive arrangement of Ï-units.
