Extraordinarily stable organic glasses are prepared by physical vapor deposition using indomethacin (IMC) or trisnaphthylbenzene. Utilizing Brillouin light scattering (BLS), the elastic moduli of these stable glasses (SG) are found to exceed those of ordinary glass (OG) by up to 19%. Such high‐modulus glasses take more than 10 4 times longer than the structural relaxation time to transform to the supercooled liquid (SCL).
