摘要：
A dramatic color change and tremendous emission enhancement have been "switched on" upon increasing diethyl ether ratio in acetonitrile or acetone solution of [Pt(tpy)(C≡C-C≡CH)]OTf, attributed to the formation of Pt⋯Pt and π-π interactions. Two crystal forms (dark-green and red) of [Pt(tpy)(C≡C-C≡CH)]OTf, together with [Pt(tBu3-tpy)(C≡C-C≡CH)]OTf, show different crystal-packing modes as revealed by X-ray crystallography.
