di-n- octylfluorenyl-2,7-diyl) (F8) and poly[(9,9-di-n-octylfluorenyl-2,7-diyl)-altthiophene] (F8T1). The protocol used can provide an environmentally friendly, safe
and mild process to rapidly produce ambidextrous light-emitting polymers with a
minimal loss of starting polymers at room temperature, made from CD-silent polymers without any specific chiral substituents or chiral catalysts.
6.3.4 Photon-Induced Chirality
It has been speculated that the r- or l-CP-photon source in γ- and X-rays, and vacuum UV regions can be responsible for the astrophysical and biological handed
on the planet Earth. The handed CP light source could have played an important
role in the prebiotic evolution biology by interacting with molecules (Inoue 1992;
Feringa and van Delden 1999; Inoue and Ramamurthy 2004). As a practical consequence, the CP photon-driven absolute asymmetric synthesis (AAS) can be referred
