This invention provides a heat dissipation structure for use in optoelectronic devices. More specifically, this technology is an innovative heat dissipation thick/thin organic-inorganic coating containing active molecularly functionalized vibrational lattice modes designed to act as a molecular cooling fan. The molecular fan is powered directly from the heat generated by the device it is cooling, so it is a powerless heat sink with a spaceless nanoassembly. The "molecular fan" is used to enhance emissivity and radiative cooling of surfaces that are processed in a coated heat-sink or substrate and in tests has lowered the equilibrium temperature of optoelectronic components by 5-12 degrees centigrade.

The vibrating part of the molecule effectively releases the heat via radiative/nonradiative processes, greatly reducing or eliminating the need for cooling by convection and mechanical fans.
