Abstract	Hypocrellins, photoactive compounds isolated from fungus, were first employed as non-surfactant templates in the synthesis of ternary chalcogenide Cu$_{3}$BiS$_{3}$ and AgBiS$_{2}$ crystallites via a facile ethanol-thermal process. It was also found that the used templates, poly (vinylpyrrolidone) (PVP), poly (ethylene glycol) (PEG), and hypocrellins had strong effect on the morphology of synthesized Cu$_{3}$BiS$_{3}$ and AgBiS$_{2}$ and their catalytic polymerization products of an alkylsilane, C$_{18}$H$_{37}$SiH$_{3}$ with water. In particular, the orthorhombic phase of wittichenite Cu$_{3}$BiS$_{3}$ with multi-armed microrods morphology and the cubic Schapbachite and hexagonal phase Matildite AgBiS$_{2}$ with flower-like morphology were obtained when hypocrellins were used as templates at 180 °C for 20 h. Although, the used templates seem to have little effect on the crystalline grain size, compared with traditional PVP and PEG templates, hypocrellins have exhibited better directing actions. Furthermore, the polymerization products over Cu$_{3}$BiS$_{3}$ and AgBiS$_{2}$ templated by hypocrellins showed good replica of the morphologies before polymerization while the polymerization products over Cu$_{3}$BiS$_{3}$ and AgBiS$_{2}$ templated by PVP and/or PEG exhibited significant morphology change.
