Photothermal (PT) properties of conjugated polymers have been attracted widely from biomedical engineering to energy conversion.  Nanoparticles and thin films of  conjugated polymers (CPs) have shown high photothermal transition, arising from their effective carrier transport plus low thermal conductivity. The molecular structure and composition of the polymer films were critical to the photothermal energy flux, which was transferred to adjacent soft polymer layer to drive mechanical displacement of a polymeric structure. Herein we present two types of photothermal heaters based on CPs and diimonium dyes as a conductive and transparent PT films, respectively. The PT films from CPs were effective for non-destructive cell sheet harvesting while those from  diimonium dyes provided the first example of transparent hot Venus flytrap. The mechanism of the photothermal energy conversion and their application potential will be discussed.
