We report a through-space electron effect (TSEE) between two phosphorescent units that significantly modulates the selective expression of ultralong organic room-temperature phosphorescence (UORTP) and photochromism. A series molecules (DNapTr, DNapBNT, DNapFL, DNapPy), featuring connected by nonconjugated spacer, were synthesized. Our findings reveal both TSEE energy gap ΔE (defined as EPU2 - EPU1) lowest triplet levels (T1) play crucial roles in determining UORTP photochromic behavior PMMA films. NMR spectra molecular simulations confirm presence TSEE, with their strength ranked DNapPy < DNapFL DNapBNT TSEE. The DNap unit is governed where moderate inhibits radical cation formation, while strong promotes it. Consequently, DNapTr, exhibit tunable photochromism, whereas remains nonphotochromic. jointly influenced ΔE. For DNapTr (ΔE > 0), excitons are trapped via leading to from DNap. In slightly <0), directs PU2. ≪ enables Py. By leveraging tuning T1 PU2, we successfully modulated photochromism UORTP. This study provides strategy for designing intelligent materials.

Macrocyclic arenes show conformational adaptability, which allows host-guest complexations with the size-matched guest molecules. However, their emission properties are often poor in solid states due to self-absorption. Herein, we newly synthesized pillar[6]arene derivatives having alternate methylene and nitrogen bridging structures. Solvatochromic study reveals that nitrogen-embedding into cyclic structures can strengthen intramolecular charge transfer (CT) nature compared of linear nitrogen-bridged precursor. Owing large Stokes shift state, one nitrogen-embedded pillar[6]arenes shows high absolute photoluminescence quantum yield (Φ
