Summary: The silylene–π conjugating polymer, poly(di‐ n ‐hexylsilylenephenylene‐ethynylenephenylene) ( 1 ) adopted a fairly flexible coil‐like conformation due to the bent structure of silylene moiety and showed a unique photoexcited energy transfer behavior. The UV‐vis absorption and steady‐state/time‐resolved photoluminescence studies revealed the occurrence of an intramolecular photoexcited energy transfer (IET) between locally excited π* to charge transfer ground states as well as an intramolecular charge transfer (ICT).The silylene–π conjugating polymer, poly(di‐ n ‐hexylsilylenephenylene‐ethynylenephenylene) showing a unique photoexcited energy transfer behavior.
