摘要:Provided is a bridged organosilane, which has a large complex organic group, and which is useful in the synthesis of a mesoporous silica and a light-emitting material, and a production method of the bridged organosilane. The bridged organosilane is expressed by the following general formula (1): n n n n n n n n n n [in the formula (1), q represents an integer in a range from 2 to 4, X 1 — represents a substituent selected from the group consisting of substituents expressed by the following general formulae (2) to (5): n n n n n n n n n n (in the formulae (2) to (5), R 1 represents alkyl group having 1 to 5 carbon atoms, R 2 represents an allyl group, and n represents an integer in a range from 0 to 3, and m represents an integer in a range from 0 to 6), and A 1 represents an organic group expressed by, for example, the following general formula (6): n n n n n n n n n n (in the formula (6), Y 1 < represents a substituent expressed by, for example, Oâ•?<)].
