1. An alkanethiol of formula (1) and the enantimomers of the alkanethiol of formula (1):


  • HS-L-Q-T 



    (1), where -L- is -(Ax-By-Ez-D)w-;

    each A, B, E and D are individually C(RARA

    )—

    , —

    C(RBRB

    )—

    , —

    C(RERE

    )—

    , and —

    C(RDRD

    )—

    , respectively;

    each RA, RB, RE and RD are individually H, or any two of RA, RB, RE and RD together form a bond, or RA, RB, RE and RD together with the atoms to which they are bonded form a six-membered aromatic ring;

    each RA

    , RB

    , RE′ and

    RD

    are individually H, or any two of RA

    , RB

    , RE′ and

    RD

    together form a bond, or RA

    , RB

    , RE′ and

    RD

    together with the atoms to which they are bonded form a six-membered aromatic ring;

    each x, y and z are individually either 0 or 1;

    w is 1 to 5;

    -Q- is selected from the group consisting of embedded image-T is a moiety of formula (2) embedded imageR1 and R2 are each individually selected from the group consisting of H and OH;

    a is 0 to 3;

    b is 0 to 3; and

    custom character indicates that the chirality of the carbon atom to which it is attached is either R or S.
