4-苯氧基苯酚是一种简单的有机分子，结晶为多孔材料，通道贯穿整个结构。通道由6重氢键环构成，可承载晶体生长过程中掺入的溶剂分子，最小通道直径为5.8-5.9埃；每个通道的每个晶胞通常包含一个溶剂分子。氢键环显示出令人惊讶的灵活性，即使在空孔生长时也能够呼吸并维持其晶体完整性。这是特别令人惊讶的，因为晶体结构内的其余相互作用是C-H中心点中心点中心点pi相互作用并且本质上很弱。还可以通过在重结晶中使用大体积溶剂来生长“干燥”多孔4-苯氧基苯酚晶体。
4-Phenoxyphenol is a simple organic molecule that crystallizes as a porous material with channels running throughout the structure. The channels are constructed by a 6-fold hydrogen bonded ring and can host solvent molecules incorporated during crystal growth, with a minimum channel diameter of 5.8-5.9 angstrom; each channel usually contains a single solvent molecule per unit cell. The hydrogen bonded ring shows surprising flexibility, being able both to breathe and to sustain its crystalline integrity even when grown with empty pores. This is particularly surprising given that the remainder of the interactions within the crystal structure are C-H center dot center dot center dot pi interactions and are weak in nature. It is also possible to grow "dry" porous 4-phenoxyphenol crystals by using a bulky solvent in the recrystallization.
