I will first present a review on several novel compounds with potential technological applications, obtained by reacting dense simple carbon bearing molecular systems at GPa or tens of GPa, strongly confined in the sub-nanopores of zeolites. On a more physical ground, confining inhert simple systems at high pressures, at the angstrom scale, produced exotic sub-nanophases of these systems. Indeed, I will show recently obtained dense sub-nanophases of rare gases and of $N_2$, $O_2$, $H_2$ and $H_{2}O$, confined in zeolites. Investigations were performed by using diamond anvil cells, optical spectroscopy, and laboratory and synchrotron X-ray diffraction, and also classical and DFT simulations.
