As a high density hydrocarbon fuel,tetracyclo［7.4.0.0^2,7.1^3,6］tetradecane was synthesized from dicyclopentadiene and indene by D-A reaction and hydrogenation. Under the optimal conditions, the yield of tetracyclo［7.4.0.0^2,7.1^3,6］tetradecane is 68.1%. Properties of tetracyclo［7.4.0.0^2,7.1^3,6］tetradecane were measured (i.e. density is 0.986 g·cm^-3, volumetric combustion heat is 43.7 MJ·L^-1, viscosity (-18 ℃) is 97.44 mm²·s^-1, flash point is 50 ℃,freezing point is -45 ℃). Thermal decomposition of tetracyclo［7.4.0.0^2,7.1^3,6］tetradecane was analyzed by DSC. Results show that tetracyclo［7.4.0.0^2,7.1^3,6］tetradecane has high thermal stability.
