| Molecular self-assembly: It is the process by which molecules adopt a defined arrangement without guidance or management from an outside source. There are two types of self-assembly, intramolecular self-assembly and intermolecular self-assembly. Most often the term molecular self-assembly refers to intermolecular self-assembly, while the intramolecular analog is more commonly called folding. Molecular self-assembly is a key concept in supramolecular chemistry since assembly of the molecules is directed through noncovalent interactions (e.g., hydrogen bonding, metal coordination, hydrophobic forces, van der Waals forces, π-π interactions, and/or electrostatic) as well as electromagnetic interactions. Common examples include the formation of micelles, vesicles, liquid crystal phases, and Langmuir monolayers by surfactant molecules. Further examples of supramolecular assemblies demonstrate that a variety of different shapes and sizes can be obtained using molecular self-assembly. |

| 分子自組裝: 這是分子在無外界干擾或者管理下采取的一種既定組織方式。自組裝有兩種方式,分子間自組裝和分子內(nèi)自組裝。分子自組裝在通常意義上偏向分子間自組裝,因?yàn)榉肿觾?nèi)自組裝一般稱作折疊。分子自組裝在超分子化學(xué)中是一個核心概念,因?yàn)閬碇笇?dǎo)分子組裝的是通過非共價鍵(比如氫鍵,金屬絡(luò)合,疏水力,范德華力,pi-pi鍵,或者靜電力)或者電磁作用力。一些基本例子包括膠束,囊泡,液晶態(tài),表面活性分子的蘭格謬爾單層。更多超分子組裝的例子表現(xiàn)了用分子自組裝可以得到很多不同形狀和大小的超分子。 |
