Structural Control of Photoconductivity in a Flexible Titanium‐Organic Framework
Advanced Materials, Volume 37, Issue 52, December 29, 2025.The concept of flexibility is extended to titanium frameworks and use it to gain control over charge transport. MUV‐35 is a flexible doubly interpenetrated framework that can shrink spontaneously its volume by ≈40% to afford a photoconductive, porous state that is thermodynamically favored by non‐covalent interactions. Abstract The soft nature of Metal‐
