N-Heteroacenes as an Organic Gain Medium for Room-Temperature Masers.

The development of future quantum devices such as the maser, i.e., the microwave analog of the laser, could be well-served by the exploration of chemically tunable organic materials. Current iterations of room-temperature organic solid-state masers are composed of an inert host material that is doped with a spin-active molecule. In this work, we systematically modulated the structure of three nitrogen-substituted tetracene derivatives to augment their photoexcited spin dynamics and then evaluated their potential as novel maser gain media by optical, computational, and electronic paramagnetic resonance (EPR) spectroscopy. To facilitate these investigations, we adopted an organic glass former, 1,3,5-tri(1-naphthyl)benzene to act as a universal host. These chemical modifications impacted the rates of intersystem crossing, triplet spin polarization, triplet decay, and spin–lattice relaxation, leading to significant consequences on the conditions required to surpass the maser threshold.

通过探索化学可调的有机材料的探索，可以很好地探索Maser的未来量子设备，即激光的微波类似物。光激发旋转动力学和然后，通过光学，计算和电子磁共振共鸣（EPR）光谱来评估它们的潜力，以促进这些投资，我们采用了一个有机玻璃，以前，1,3,5-tri（1-萘基）苯苯苯苯苯苯苯甲酸含量上的散发效果，旋转了旋转的速度。需要超过Maser阈值。
