Search Compounds by Mesophase:
A search which can be carried out to produce liquid crystals with similar/identical phase behaviour.
The family search of phases will broaden the search to corresponding phases so that for example SmecticA (A), TGBA (A#), Re-Entrant SmA (Are) will all be found. Its also possible to specify 'S' for any smectic phase.
Search by Line Notation:
This search involves entering an abbreviated molecular formula and is best used for simpler liquid crystal structures.
If for example you search for the following molecule:
You must first convert it into its line-notation:
Now this can be entered as a search string
Search by Fragments:
This search allows you to build up a liquid crystal structure in the form of specific segments of the molecule as precisely as required. A display of all molecules that fit the criteria will be produced.
To search for the structure:
the following details should be entered into the 'Search by Fragments' - window:
Search by Classification:
A very general search in which groups of liquid crystals are searched for which obey certain pre-selected molecular classifications.
In the example below, you search for liquid crystals that undergo a ferroelectric phase, possess a calamitic, symmetrical phase but don't undergo a discotic phase.
