Tecton strategy

The viability of the strategy based on the use of concave and convex molecular tectons to generate inclusion networks in the crystalline phase was demonstrated. A further step consisting in designing directional inclusion networks was also shown. However, so far noncentrosymmetric packing of the linear directional arrays has not been achieved. This remains a challenge. In principle, if the latter... 

Although the crystallization process for strategies 1-4 inherently affords homochiral single crystals, only the use of homochiral tectons guarantees that all crystals will be of the same enantiomorph. Indeed, batches of crystals will often be heterochiral as both enantiomers tend to be formed equally during crystallization. Fortunately, it has been demonstrated58 that formation of homochiral bulk materials can be afforded by seeding with the desired enantiomer.
