  • The energy transfer from photoexcited polyvinylcarbazole (PVK) chromophores with a bandgap of 3.7 eV as a donor to fluorophores of poly(dihexylfluorenevinylene) (PDHFV) or poly(dihexylfluorenedihexoxyphenylenevinylene) (PDHFHPV) as an acceptor in bilayered specimens should be carried out since the spectral overlap pairs fulfills the requirement for the $F{\"{o}}rster-type$ condition. However, the energy transfer rate from the chromophores with a wider bandgap to the fluorophores with a narrower bandgap is proved to be strongly dependent on the lifetime ratio between the excitons.

  • 고체상 site-specific mono-PEGylation 공정은 액체상 PEGylation 공정에서 나타날 수 있는 무작위적인 multi-PEGylation 문제점을 해결하고, 또한 고체상에서 PEGylation을 수행함으로써 액체상 PEGylation 공정에서 필요한 분리정제 단계를 줄일 수 있음을 제시하였다.
