Removal of “Majority-Rule” and “Sergeant-Soldier” Polysilane Scaffold from the Hetero-Aggregation System Consisting Circularly Polarized Polydioctylfluorene

Abstract

The “majority-rule” and “sergeant-soldier” principle action containing either or both non-charged chiral helix of both Poly (n-hexyl-(S)-2-methylbutylsilane) (PSi-S) and poly (n-hexyl-(R)-2-methylbutylsilane) (PSi-R) were employed as scaffold to determine the polymer capability to amplified chiral shape to the achiral poly (9,9-di-n-octylfluorene) PF8 in a hetero-aggregate system. The majority-rule polysilane refers to the PSi-R-ran-PSi-S copolymers with excess copolymers of R or S in a copolymer system. Meanwhile, the “sergeant and soldier” polysilane was described as PSi-R(S)-ran-PSi-iBu copolymers when one chiral element imposes its screw sense on a large “platoon” of achiral copolymer fragments. For PSi-R-ran-PSi-S copolymers, the effect is rather small featuring PF8 small monotonic increase along with the percentage of back-bone chiral unit. In PSi-R(S)-ran-PSi-iBu copolymer systems, the helix inversion is more obvious in which the PF8 followed the PSi chiral screw preferences.
