Abstract Organic cocrystals possess valuable properties owing to the synergistic effect of individual components. However, growth molecular is still in its primary stage. Here we develop a microspacing in-air sublimation method grow organic cocrystals, and furthermore realize morphology control on them, which essential for structure–property relations.

Organic single crystals manifest the intrinsic physical properties of materials. However, traditional growth organic is limited by low solubility from solutions or complexity vapor deposition. Here we report a new method to grow microspacing in-air sublimation, which avoids costly vacuum system and time-consuming procedures practical for wide range crystals.

Although room-temperature phosphorescence (RTP) organic materials are a widely-studied topic especially popular in recent decades, long-lived RTP able to fulfil broad time-resolved application requirements reliably, still rare. Polymeric doped with phosphorescent chromophores generally feature high productivity and diverse applications, compared their crystalline counterparts. This study proves that pure polycyclic aromatic hydrocarbons (PAHs) may even outperform containing hetero- or...
